Пара-крезилфенілацетат

Animalic-floral, leathery, and narcotic. Para-Cresyl Phenyl Acetate (PCPA) smells like the dark underbelly of narcissus — a creamy, slightly fecal floralness that gives white flowers their indolic depth.

Цікавий факт
Para-cresol, the parent compound of PCPA, is one of the primary odorants in horse manure. The fact that the same molecule (in diluted, ester form) is essential for creating beautiful jasmine and narcissus accords is one of perfumery's most counterintuitive truths.

У парфумерії
PCPA is a trace ingredient used as an animalic modifier in floral compositions. It adds narcotic depth and naturalistic complexity to white flower accords — jasmine, tuberose, narcissus, orange blossom. Functions at very low concentrations (0.01-1% of a formula). Essential for creating convincing natural-style florals. Used in amber, floral-animalic, and niche compositions. Part of the 'dirty floral' toolkit alongside indole, skatole, and costus.
